On the other hand, if you didn't see Blue, White (SDloader Mem
write), then Yellow on your LED, and your console either boots
to a black screen, or instead boots to OFW like normal, then
look at the following LED code list to diagnose your potential
issue:
= is long Yellow pulse, * is short Yellow pulse:
= USB flashing done, * Successful glitch
** RST is not connected
*= CMD is not connected
=* D0 is not connected
== CLK is not connected
*** No eMMC CMD1 responce (bad eMMC?)
**= No eMMC block 1 read (should not happen)
*=* No eMMC block 0 read (eMMC init failure?)
*== No eMMC CMD1 request (poor wiring, or dead CPU)
=** eMMC init failure during glitch process
=*= CPU never reach BCT check, should not happen
==* CPU always reach BCT check (no glitch reaction, check
mosfet)
=== Glitch attempt limit reached, cannot glitch
=*** eMMC init failure
=**= eMMC write failure - comparison failed
=*=* eMMC write failure - write failed
=*== eMMC test failure - read failed
==** eMMC read failed during firmware update
==*= BCT copy failed - write failure
===* BCT copy failed - comparison failure
==== BCT copy failed - read failure
